Title: Method for measuring the frequency of an alternating voltage
Inventor: OBERDOERFER EUGEN W ING GRAD
IPC: G01R23/10
Filed: 1981-12-08
Abstract: In this method, a time interval is determined in each case by means of control pulses obtained from the alternating voltage. To create a method which allows the frequency to be measured with high accuracy, a timing stage (9), which is triggered with the beginning of each period of the alternating voltage (Um), is used which has a timing period which corresponds to the shortest expected period of the alternating voltage (Um). After this timing stage (9) has timed out, a subsequent counter (7) is started into which pulses of a clock generator (11) are counted until the end of the period monitored in each case is indicated by a control pulse. From the count, the frequency is calculated in an arithmetic unit (16). The invention can be used with frequency relays. <IMAGE>

Title: Service water heater and waste gas heating body which are operated with waste gases, with a heat accumulator and fan operated by waste heat
Inventor: LUTZENBERGER HELMUT
IPC: F24H1/20
Filed: 1981-12-21
Abstract: A normal wood, coal, gas or oil stove is required. At the respective waste gas outlet of the stove, a curved stovepipe is located (with waste gas heating body a T-piece stovepipe with muff and built-in regulating flap). The service water heater pressure boiler is located on the vertical branch with muff. In the service water pressure boiler, the spiral waste gas passage leads further to the other end of the pressure boiler, after which a stovepipe conducts the waste gases further into the flue. On the horizontal branch of the T-piece with pressure boiler connection, the waste gases, according to the setting of the regulating flap, run through the waste gas heating body, and after this again into the flue. Built into the T-piece pipe branch is a regulating flap. Located on this waste gas heating body is a very flat, pyramid-shaped covering, into the centre of which a fan is built. This fan is automatically driven by heat emission of the waste gas heating body and of the arising automatic air suction laterally from the rear.

Patent DE-3207131-A1 (DE)
Inventor: ALPEN ULLRICH VON DIPL PHYS DR
IPC: H01M6/18
Filed: 1982-02-27
Abstract: By use of new ion conducting but non-electron conducting mixed crystal compounds of the type sodium zirconium phosphatosilicate as the ceramic board material for electronic circuitry it is possible to provide full integration of electronic, electro-chemical and optical components, because the boards simultaneously constitute the solid electrolyte for the miniaturized batteries serving as energy source, and for an electrochromic display system. An illustrative practical embodiment involves housing within a ceramic multi-layer structure a battery with positive electrode and negative electrode for a quartz driving circuit and an electrochromic (ECD) display controlled by an microprocessor. For the flow of current through the ECD there is used a secondary element formed of a WO3 electrode and a Na-tungstenate electrode as the counter electrode, the WO3 segments assuming a blue color due to diffusion of Na+ ions.

Title: Method and device for operating a traffic-light system
Inventor: GRUETZBACH HANS
IPC: G08G1/07
Filed: 1982-05-17
Abstract: In a traffic-light system, which consists, for example, of two traffic lights set up at both ends of a building site in order to control alternating single-file traffic, the problem exists of setting the two lights in a mutually dependent fashion to a prescribed phase sequence and phase length. The traffic lights are equipped with in each case one clock-pulse generator, one programmed control sensor and one such operating current source. The aim of such a light system is to simplify and improve the synchronisation of the lights and make it less susceptible to faults without a relatively large outlay on equipment. This is achieved when the control sensors of all the lights are programmed for their phase sequence and phase length relative to the other lights individually and independently of one another, and the programmed but not yet switched-on control sensors are put into operation by a central radio signal. A central transmitter, which can be arranged either independently of the lights or else in one of the lights, is provided for transmitting the switch-on pulse.

Patent DE-3236230-A1 (DE)
Title: Transparency with an optically diffusing layer and process for the production thereof
Inventor: HAAG ANTON
IPC: B44F1/06
Filed: 1982-09-30
Abstract: A transparency is provided, in which a transparent base (1) consisting of plastic material is provided, on one side, with an image coating (2) in the developed condition and a transparent optically diffusing layer (3) is provided subsequently, parallel to the base provided with the image coating. In this case, it is desired that the transparency, in spite of the transparent base, should be capable of being produced with a light optically diffusing layer while avoiding the storage of separate material specifically required for this purpose. This is achieved in that the optically diffusing layer is an applied lacquer layer (3), known per se, having a high degree of transparency and containing microscopically small highly transparent spheres (5). The combination of the transparent base with the microsphere lacquer leads to the avoidance of the storage of photographic material with an opalescent base film and of the use of heavy opal plates or diffusing films. <IMAGE>
